Exploring the Meaning of Katallage in Greek

καταλλαγή refers to “reconciliation,” a restored relationship described as something received, announced, and entrusted. It appears in Romans and 2 Corinthians in contexts that speak of God’s action “through our Lord Jesus Christ” and “in Christ,” and of a resulting message and ministry.

Root and Related Words

καταλλαγή is related to the verb katallassō (καταλλάσσω), “to reconcile.”

Occurrences

“Not only so, but we also rejoice in God through our Lord Jesus Christ, through whom we have now received the reconciliation.” (Romans 5:11)

Here reconciliation is spoken of as something already received: “we have now received the reconciliation.” The sentence frames it as a present possession that produces joy—“we also rejoice in God”—and it is explicitly mediated “through our Lord Jesus Christ.” In this verse, reconciliation functions as the settled basis for rejoicing, not merely as an idea: it is an obtained benefit that changes the stance of the worshiper toward God (“rejoice in God”).

“For if the rejection of them is the reconciling of the world, what would their acceptance be, but life from the dead?” (Romans 11:15)

In this setting, reconciliation is scaled to the level of “the world” and is linked to large movements described as “the rejection of them” and “their acceptance.” The word stands for a broad reconciling outcome that extends beyond one individual or group: “the reconciling of the world.” The verse places that reconciling alongside a rhetorical contrast—rejection versus acceptance—and uses it to heighten expectation: if rejection correlates with the world’s reconciling, acceptance would correspond to something even more climactic, described as “life from the dead.” Reconciliation is thus treated as a world-reaching effect within God’s unfolding dealings.

“But all things are of God, who reconciled us to himself through Jesus Christ, and gave to us the ministry of reconciliation;” (2 Corinthians 5:18)

This verse sets reconciliation inside a chain of divine initiative: “all things are of God.” God is the acting subject—“who reconciled us to himself through Jesus Christ”—and the relational direction is explicit: “to himself.” Reconciliation is not only an accomplished act affecting “us”; it also generates a commission. The same verse speaks of an entrusted role, “the ministry of reconciliation,” showing that reconciliation is not only received (as in Romans 5:11) but also carried outward in service. The wording connects the reconciled status of a community (“us”) with its vocation: those reconciled become agents in a ministry characterized by reconciliation.

“namely, that God was in Christ reconciling the world to himself, not reckoning to them their trespasses, and having committed to us the word of reconciliation.” (2 Corinthians 5:19)

This statement expands the scope again to “the world” and describes reconciliation as God’s action “in Christ”: “God was in Christ reconciling the world to himself.” The verse also pairs reconciliation with a negative description—“not reckoning to them their trespasses”—so that reconciliation is associated with God’s refusal to count trespasses against those being addressed (“to them”). In addition to the act itself, there is an entrusted message: God has “committed to us the word of reconciliation.” The verse thereby distinguishes between reconciliation as God’s reconciling work and reconciliation as a spoken or proclaimed content (“the word of reconciliation”) placed into the care of “us.”

Sense and Usage

Across these passages, reconciliation is consistently relational and directional: it is reconciliation “to himself” (2 Corinthians 5:18–19), and it is received “through our Lord Jesus Christ” (Romans 5:11). The term is used both for an experienced reality (“we have now received the reconciliation”) and for a world-embracing work (“the reconciling of the world”; “reconciling the world to himself”). This combination keeps the sense anchored in restored relationship while allowing for different horizons—personal reception, communal identity (“us”), and global scope (“the world”).

The word also carries an entrusting dynamic in 2 Corinthians. Reconciliation is not confined to what God has done; it becomes the defining character of what God gives: “the ministry of reconciliation” (5:18) and “the word of reconciliation” (5:19). The “ministry” language casts reconciliation as the aim and shape of service, while the “word” language treats it as a communicable announcement. Taken together with “not reckoning to them their trespasses,” reconciliation here is tied to the way God relates to human wrongdoing—not by counting trespasses against “them”—and this framing supports why a message about reconciliation can be committed to others: it is news about God’s reconciling posture “in Christ.”

Romans emphasizes the response reconciliation elicits. In Romans 5:11, reconciliation is something received that leads to rejoicing “in God,” and the mediation “through our Lord Jesus Christ” places reconciliation within a christological pathway. In Romans 11:15, reconciliation sits within a sweeping argument that contrasts “rejection” and “acceptance,” using reconciliation’s world-effect to reason about what greater outcome might follow. In both Romans and 2 Corinthians, reconciliation is not described as a human achievement; it is framed as something that comes through Christ and proceeds from God’s initiative.

Imagery in Context

The passages attach reconciliation to concrete movements: receiving (“have now received”), giving (“gave to us”), committing (“having committed to us”), and reckoning (“not reckoning to them their trespasses”). These verbs supply the imagery: reconciliation comes as a gift already in hand (Romans 5:11), it reaches outward as a world-level act (Romans 11:15; 2 Corinthians 5:19), and it becomes a stewardship—both a ministry and a word—placed into the custody of those who have been reconciled (2 Corinthians 5:18–19).
